How Much Does A Crawl Space Drainage System Cost?

Read Time: <3 minutes

Table of Contents

If you have standing water in your crawl space, or your crawl space floods or gets wet when it rains, then you need for a crawl space drainage system. This system involves digging a trench around the inside perimeter of the space, either the full perimeter or just a section, depending on where the water is coming from. The trench will lead to a sump pump that will collect any water and then redirect it safely away from the space.

A common question that we get asked is how much does a crawl space drainage system cost? There are a number of factors that influence how much a crawl space drainage system costs. Watch the video or skip to the article below to keep reading.

What Factors Affect Crawl Space Drainage System Costs?

THE HEIGHT OF THE CRAWL SPACE

Digging a trench and generally working in the crawl space will be much easier and go more quickly when the space is tall enough for our crew members to freely move around. If the space is tight, so less than 2 feet tall, it will be more difficult for them to maneuver, thus adding to the time involved, and increasing the crawl space waterproofing cost.

THE SIZE OF THE CRAWL SPACE

One of the biggest cost factors is the size of the crawl space. If your crawl space is 1,500 square feet, it will take less time and materials than installing a drainage system in a crawl space that is 3,000 square feet. Our crews get an accurate measurement of your crawl space when estimating the job so they can give you an accurate estimate.

FULL OR PARTIAL CRAWL SPACE DRAINAGE SYSTEM?

Costs will vary depending on whether you need a full drainage system, meaning the trench needs to be dug around the entire perimeter, or a partial system. There are some situations where the trench is only needed on one or two walls. Since we price on linear footage, less footage means a lower cost.

IS GRADING REQUIRED?

The majority of the time, if grading is required it’s relatively simple and doesn’t affect the price. However, if the terrain in your crawl space varies, sloping upwards in some areas, we may have to correct that in order for the water to drain properly to the sump pump. Water can not drain uphill. On the very rare occasion, terrain differences may require more than one sump pump, adding to the cost.

DO YOU WANT A BATTERY BACKUP?

In order to keep the crawl space dry, the sump pump must be kept operational. It is a stipulation in our warranty coverage. For that reason, many homeowners choose to install a battery backup system in the event of a power outage. While most outages do not last long, they also often occur during a storm and are accompanied by a lot of rainwater. If your crawl space floods during a heavy downpour, the last thing you need is for the sump pump to not be operational.

So How Much Will a Crawl Space Drainage System Cost?

Though we cannot give you an exact cost of a crawl space drainage system without having all of the information from the above factors, we can provide a rough estimate based on the average cost of past jobs. The average cost to install a crawl space drainage system in a 1,500-square-foot home is between $5,200 and $5,500. A battery backup system is optional and will cost roughly an additional $1,200.
